    Without knowing how hard you drive, 36mpg isn't disastrous, but I'd be disappointed.

    EGR valve not closing?
    Blocked or poor quality air filter?
    Slipping clutch?

    Is it running OK performance wise? Starting OK? Excessive exhaust smoke?

    Change all the filters and give it an oil change.
    Also check that brakes aren't binding and tyres are inflated correctly.

    ^Brake binding is an excellent point! This happens quite a lot...

    The back calipers on the tourer seem to be prone to water ingress, when I stripped mine they had a lot of rusty crap inside, I just rebuilt them with a load of red rubber grease in the grooves where the seals sit so hopefully they won't be able to hold water as easily now.
    The air filter is something worth checking, the diesel airfilter is pretty small surface area and responds well to a new filter, the Honda one seems to be a kind of oiled flock.

    Also if your the type that drives around with a bunch of stuff (weight) in the boot have a clear out. Doing the same drive empty on the Fit- 17.4 km/l, with 70kg of dog 15.3 km/l I was surprised that it made such a large difference in economy.

    36 MPG is my average on the ICTDI FR-V. Going over 60 on the motorway just kills the MPG.

    Filled mine today, averaged 47.8 MPG over 570 miles. Not bad for a big wagon.
    Onboard said 50 avg so 2.2mpg out overall.
    New airfilter makes a big difference I feel.
    Cleaned my EGR a while back it was nearly blocked just have to do the intake manifold when I get a chance and its should be even better.

    Ha ha ha ha ha ha ha ha ha ha ha ha. What a very helpful suggestion!

    The anti-diesel brigade that lurk in HK's dark corners are getting more desperate...

    Are you going under 70mph on the motorway?

    Not that much motorway on the last tank, fast country roads mainly, up to 90-100 in places but averaging around 40 going by the avg speed readout.
    Motorway at 90 I was getting 42mpg with a car full of people and luggage.

    MPH or KPH?

    I still think in both and wind up saying 50 when I mean 80 and so on. If your numbers are all in MPH that is fantastic fuel economy, above 112KPH in the flat my fuel economy dramatically shrinks. A bit past 120KPH and it drops to about 4-5km/l, enough that even a short blast really messes up the total for the tank.....then again mine has the aerodynamics of a brick.

    All in Imperial, mines a UK car so I just use the big numbers on the dash rather than the smaller Km/h.
    I still haven't found out how to change the range and other functions from Imp to Metric or if its even possible.
    Motorway run was from Leixlip to Cork.
